BACKGROUND

1. Field of the Invention

The present invention relates to a water guard system and, moreparticularly, to a water guard system having a variable height and/orwidth.

2. Brief Description of Related Developments

Sub-Floor drain conduit water control systems are used for channeling,collecting and expelling ground water from beneath the floor ofbasements or other rooms. One such system in U.S. Pat. No. 5,501,044which is hereby incorporated by reference in its entirety, discloses awater control system. In this example, a conduit housing directs waterfrom the wall—footing interface to an appropriate drainage path. Othersystems, such as in U.S. Pat. Nos. 4,245,443 and 4,745,716 which arehereby incorporated by reference in their entirety, disclose watercontrol systems where a channel member is provided between the floor andthe wall and a drain pipe is provided below the footing. In theseexamples, water is directed to the pipe through the fill between thefooting and the pipe. A problem arises when there are inconsistencies,for example in floor thickness or footing shape or height. Here, thechannel member may not be installed consistently to provide a suitabledrainage path. A further problem arises when the fill does not provide asufficiently porous path for the water. Accordingly, there is a desireto provide a drainage system whereby geometric inconsistencies may beaccommodated where the drainage system provides an open and efficientdrainage path for the user.
